Furthermore, in the lighting fixture 1 , the accommodating portion 20 has a second power supply hole 204 into which the second power supply line 6 electrically connected to the terminal block 42 is introduced. The terminal block 42 is arranged so that the first insertion hole 421 of the housing 420 faces the second power supply hole 204. Here, "facing the first insertion hole 421 and the second power supply hole 204" means that the second power supply hole 204 is provided on the front side of the housing 420 of the terminal block 42 in the width direction of the housing section 20. This means that it is directed toward the rear of the housing section 20.

Therefore, by arranging the first insertion hole 421 to face the second power supply hole 204, the lighting fixture 1 becomes necessary in the housing part 20, for example, compared to a case where the first insertion hole 421 faces downward. The extra length of the second power supply line 6 can be reduced. As a result, the lighting fixture 1 can reduce the space for accommodating the extra length of the second power supply line 6 in the accommodating portion 20, and can suppress the increase in size of the fixture main body 2.

By the way, in the fixture main body 2 of the lighting fixture 1, a first power supply hole 203 into which the first power supply line 5 is introduced and a second power supply hole 204 into which the second power supply line 6 is introduced are independently provided. Therefore, compared to the case where the first power supply hole 203 and the second power supply hole 204 are shared by one hole, the lighting fixture 1 makes it easier to route the first power supply line 5 and the second power supply line 6 within the fixture body 2. Further simplification can be achieved.
